Application August 25,

In Germany Se 15 Claims.

'I'his invention concerns tabulating machines and more particularlymachines of the class in which perforated record cards control thepreparation of account sheets or ledgers.

The main object of the invention is to provide a posting mechanism fortabulating machines or the like, in which provision is made forselectively feeding classied ledger sheets to a posting or printingdevice for receiving data of the same classification.

The invention is shown as `applied to a tabulating machine of the typedisclosed in Patent #1,762,145 in which the usual perforated Hollerithrecord cards are fed through the machine and the perforated data thereonanalyzed and used to control the operation of accumulating and printingmechanism. Ledger cards having. perforations representing classicationdata are fed through the posting mechanism concurrently with the feedingof record cards through the tabulating machine. The data of the recordcards is compared with the classification data on the ledger cards andif they are in agreement posting will take place on a selected line oi'the ledger card under control of further perforations inthe record card.

'I'he ledger card is of lines upon which p adjacent to the linesforation is made to been made on the Mechanism is provi provided with aplurality rinting is to be effected and is a column in which aperrepresent that an entry has corresponding printing line. ded to sensethe special perforations to determine upon which line of the ledger cardthe next entry is to be made.

A further arrangement of the invention provides for the feeding of agroup of record cards through the tabulating machine. Ledger cards, ofwhich there is one for each group of record cards are sent through theposting device and, upon agreement of the classification data of thefirst record card of a-'group with the corresponding data on the ledgercard, further feeding of the latter through the posting device isinterrupted and successive entries will be made thereon under control ofthe several groups of record cards. The ledger sheet is advanced step bystep or line by line to receive each entry on a diiferent printing line.

Further and other objects and advantages will be hereinafter set forthin the accompanying specification and claims, and shown in the drawings,which by way of illustration show what is now considered to be thepreferred embodiment of the invention.

Gears I! are carried at theextremity ofcardfeedroller shafts 4I which are adapted to convey the Y ledger cards L fromtheir feed magasine vertically downward into cooperation with theprinting platen 44 (see also Pil. 6).

'Ihe uppermost feeding roll shaft 43 (Fig. 4) carries a spur gear 44which meshes with an idler 45 which in turn drives a gear 4I upon whichis carried an eccentric pin 41. A link 48 connected to pin 41, hasconnection at its other end with the card picker knife 49 of the usualtype. The action is such, that, for each revolution of gear It, pickerIl will move one card downwardly from the magazine and into engagementwith the first set of feed rollers. l0

Referring now to Fig. 6 analyzing brushes 5l and cooperating contactroll 5i are located in the pathoftheledgercardLandareadaptedto analyzeindex point perforations in such card as it passes thereby. Movement ofthe index point l5 positions of the ledger cards past brushes 5l issynchronized with the movement of the corresponding index pointpositions of the record card RpasttheupperbrushesUBof thetabulatllmachine. A comparison is made between the zo datasensedbythebrush 5IandUB andifthey are found to be in agreement further feeding oftheledgercardLwillbelnternlptedandtheledgercardwillbeheldincooperaonwithplaten sothatprintingmaytakeplace oftheledgerzs cards imder control of other data on the record card R.

Astheledgercardisadvancedtowardtheplatenuand pitioned toreceive printing upon the proper line, the corresponding record card Ris being advanced past the lower brushes LB which will control thepotioning of the printing mechanismintheposting sectionofthe machine.

The manner in which further feeding ol the ledgercard L is interruptedwill now be explained. Roller shaft a (Figs. 4 and 5) disposedimmediately above platen 44 has driving connection with vertical shaft4I through a friction clutch comprising a driving member l2 im on mit uaand insegni with s worm u 5 alsolooseontheshaftandinmeshwitha threadedsection of shaft 4l. Keyed to shaft 43a and slldable axially thereon isa driven member N urged into engagement with driving member w 52 by aspring 5l. A magnet il upon energization will attract its armature i1 torock a rod 5l which carries upstanding arms 5l whose free ends carryrollers Il. 'Ihe rollers ride in a suitable groove in member Il andserve to withdraw 55 the member from engagement with driving membe l!when magnet Si is energized.

After printing has been effected on the ledger card it is removed fromprinting position by the following mechanism. Shaft a has secured 00thereto a gear il (Fig. 5) meshing with an idler I2 which in turn mesheswith a gear carried by the roller shaft b below platen 44. A motor Il(Fig. 4) carries a ratchet at the extremity of its shaft and throughpawls 68 is adapted to drive a gearll to which the pawls are pivoted. Anidler 0I serves to furnish driving connection between gears 6l and O1.Current is supplied to motor 64 after posting has been ef- 70 fected andwhile clutch 52, 54 is disengaged so that roller shafts 43a and 43h mayfeed the card downwardly to the discharge magazine. It is to be notedthat shaft 0b does not have connection with vertical shaft Il. A

resepct to the leading edge thereof upon which printing is to beeffected. To. this end a contact roller 18 and a conact block 1| (Fig.6) which are disposed in the path of the descending ledger card L may beadjustably positioned up and down so that the leading edge of the cardwill engage roller 18 when a selected line of the card is in printingposition. Upon such engagement a circuit through 18 and 1| is opened,resulting in energization of magnet 56 in a manner to be set forth inconnection with the description` of the circuit diagram. Roller 18 andblock 1| are carried by a plate 12 which extends through the side frameof the machine and connects to a block 1I (see also Figs. 10 and 11)which is guided for vertical movement in suitable guides 15.

Block 14 has an-extension 15 terminating in a handle 11 which cooperateswith a fixed scale 18. Pivoted to handle 11 is a locating and indicatinglinger 18 which cooperates with a plurality of holes 88 in the plate 18.

Block 18 may be locked in any vertical position represented on scale 18so that the connected roller 18 and block 1I may be variously positionedwith respect to platen M. Block 14 has a v cam surface 8| integraltherewith which, when the block is in lowermost position is adapted tocooperate with a spring blade 82- to move the same towards the left toopen a pair of contacts 88. Opening of contacts magnet 56 in a mannertobe more fully set forth in connection with the circuit diagram whereinthis feature of the invention will be more fully set forth.

Referring now to Fig. 17, the ledger card L may be provided with acolumn indicated at 8l in classes of work this perforation is used todeter` mine the relative position of the ledger card with respect .o theplaten u.

Referring to Pigs. 7 and 11 a special brush 85 and cooperating contactblock 88 are disposed in the path of column 84 and arranged on theprinting line. As the ledger card moves downwardly through the feedingrollers the engagement of the perforations ,in column 88 with brush 85will complete circuits which. as will be explained in 8 8 will disableclutchl '|28tooscilla.

A plurality of type vertical reciprocation bars |83 are arranged for andmay be differentially The type bars |88 arev connected to the crossheadmember |85 through theusual resilient connection comprising arms |86whose free ends abut the lower ends of the type bars and which are 25held in such engagement by springs |81. As the crosshead |85 is movedupwardly, the type bars springs |81 and arms |86. Printing magnets |88will, upon energization, attract its armature 30 |89 to draw call wire||8 toward the right to release a latch so that a stopping pawl ||2 mayberocked by spring ||8 into the path of he teeth IH integral with thetype bar |83.

Crossbead III may also beoperated under control of a cam |31 mounted upon a shaft |33 which isadapted to be operated under control of the total taking and resettingmechanism of the tabulating machine. A roller |33 cooperating with cam|32 is carried by an arm |35 loosely pivoted on shaft I |1 and havingadjustable screw connection |36 with double arm |3| rigidly secured toshaft |I1. This manner of connection to shaft ||1 is usual in the artand permits shaft I |1 to be rocked by either cam Ill mounted on shaftIl or cam |32 mounted on shaft |33.

Upon the completion of the upward movement of crosshead |05 printingfrom the selected type will be effected in the following manner.

Arm llt has secured thereto (Fig. '7) a member |38 which, as the arm III rocks in aclockwise direction, is adapted to engage the end of a pawl|39 carried by the hammer tripping bail structure |30. Bail |43 willthereupon be rocked in a counterclockwise direction against the tensionof its actuating spring lli. Printing hammers |32, pivoted at |33, arenormally spring urged into engagement with bail I so that as the bail isretracted the hammers will move away from the type element |04. As themember |33 reaches the extremity of its movement, pawl |33 will bereleased and spring III willv-actuate the bail |43 in a clockwisedirection urging the hammers |32 forcibly to eifect printing the typeelements I from those types which are positioned at the printing line.

Pawl |39 is resiliently connected to bail Ill to permit the arm |33 toby pass the pawl upon its return or downward movement. In Fig. '1 isshown the mechanism for effecting a punch operation in column Il of theledger card L as an accompaniment to each printing operation.

Punching mechanism Located directly above the analyzing element l5 whichsenses the perforation in column Il of the ledger card is a punch I anda cooperating die |45. In axial alignment with the punch I is a plunger|33 carrying a roller |31 at one end thereof.

A vertical bar I Il having rollers |43 at its lower end is disposed inthe path of movement of an arm 5I extending from bail III. As the bailis rocked in a counterclockwise direction to extend spring III, bar |43will be elevated and a camming element |52 pivoted thereon at |33 willbe elevated from its full line position as shown in Fig. 7 to its dottedline positi' rockin through substantially 90' in a counterclockwisedirection asitpasaesfromthefulltothedottedlineposition.

On the downward stroke of bar |33 a camming surface |54 of member |52will engage roller |31 to positively move plunger |33 toward the leftinto engagement with punch |44 to cause aperforationtobemadeintheledgercard. This punching mechanism may bedisabled, if desired, byrockingahandle Ilocatedontheoutsideofthemachinefromthepoaitionofl'lg.'1 tothat arranged in the ameShiftingofhandle Illtothepoaitionofl'ig.8willcausecamlfltoermgemdrncklltothepositionahowninwhichtherccim'odmofthebarlllwillmovetbememberllipaatrolkrl" in both directions, without movingthe roller mmcientlytoacmaiethepunch.

Comparing mechanism For the purpose of comparing the classification dataon the ledger card with similar data on the record card the mechanismshown in Figs. 6, 13 s and 14 is provided. Two sets of such mechanismsare utilized in the machines each of which comprises a plurality ofdifferentially settable bars l adapted to be positioned under control ofmagnets Ill which upon energization attract 10 the armatures |62 to drawcall wires |63 toward the right to release the stopping pawls |34 sothey may be rocked into engagement with the teeth lli integral with barsIBO.

A crosshead |66 of one unit (Fig. 14) is vertiil cally movable uponguide rods |61 and is adapted to move upwardly under control of a cam|63 which cam cooperates with a roller |63 carried by its follower arm|13 secured to shaft |1|. The shaft I1| has arm and link connection |12with 2o the crosshead I shown in Fig. 14.

Cam |63 (Fig. 4) is mounted upon a shaft |13 which also carries abevelled gear |13 meshing with a bevel gear |15 secured upon an obliqueshaft |16 whose upper end (see Fig. 9) also car- 25 ries a bevel gear|11 meshing with a bevelled gear |18 integral with gear 20. It will berecalled that gear 2l may be disengaged from driving relationship withthe gear I9 and due to its manner of connection with shaft |13 as justex- 30 plained the latter shaft will also cease operation together withgear 20 when the latter is disengaged from gear I3. In Figs. 6 and 14the crosshead Ia of the second unit is driven from a cam la carried by ashaft |130.. Shaft |13a 35 has bevel gear connections |13a, |15a with ashaft |164 whose upper end has bevel gear connections |11a, |1la (Fig.9) with shaft Il. It will thus be apparent that one of the units willoperate continuously as long as shaft I3 oper- 40 ates while the otherwill only operate when the gear 2l is coupled to the gear Il andconsequently to the shaft i3. Referring again to Fig. 14 each bar Icarries a contacting member |33 at its upper end. This member, movesupwardly is adapted to successively connect a series of insulatedcontact blocks I3 I with a common conducting bar`l32. The blocks |3| ofFig. 14 correspond in number and in position to the index pointpositions in which classiiication data are perforated on the ledgercards and contact Ill is adapted to be set under control of theseperforations to connect the block Ill corresponding t( the perforationin a particular card column with the common bar |32. The contact bar |33'of the second unit (Fig. 6) will be similarly positioned under controlof the upper brushes UB of the tabulating machine to position contactIll in connection with the block |3| corresponding to the perforationposition of the selected column of the record card. The manner in whichthe setting of the several bars I and contact blocks lll control thecomparison ofthereeordcardsRwiththeledgercardsLwillbemorefullyaetoutinconnectionwiththec explanation of thecircuitdiagram.

Thesefunctions do not enter specifically into the present invention and willnot be deviously mentioned.

Associated with each adding wheel is the usual magnets |9| when totalprinting is to be eifected. A representative circuit may be traced asfoli lows: from` positive rside oi line 203, through Azero buttoncontacts 220 (which are closed when total printing is desired from theassociated counter) wire 22|, contacts 2|9, printing magnet |9|, wire 2|l, lower contacts LPI (closed during total 30 i printing operations)switch 2|6, contacts 2|1 to right or negative side of line 2|2 asbefore.

The mechanism and circuits just described and traced are set forth inmore particular detail in the patents mentioned to which reference may35 be had for further detailed disclosure, and, since such mechanismforms no part of the present invention further explanation thereof isnot necessary here.

It has been briey pointed out how data may be read from record cards andentered into the o during total taking operations, the accumulated 5data may be read from the accumulators and caused place during totaltaking operations.. This arrangement is in accordance with the wellknown method of operating tabulating machines of this character. i

Posting on a predetermined line The operation of the entire apparatuswill now be described in connection with the printing on a predeterminedline of each ledger card of data o corresponding record card. Ledgercards and record cards both arranged in the same sequential order areplaced in their respective magazines after which, a switch 222 (Fig.16a) is closed thereby completing a circuit 35 through the magnet ||9,from line 299, through the switch to line 2|2. It will be recalled thatin tabulator.

'I'he printing line selecting devices of Fig. 10 are u -gizedinthosepositioned in accordance with the line upon which printing is desired tobe effected.

Referring now to Fig. 16a, a plurality of control relays 222 areprovided which are connected in series between a corresponding number ofplug sockets 224 and 222. The sockets 222 may be connected by suitableplug connections 222 to sockets 221 associated with the ledger cardanalyzing brushes l2. Plug sockets 224 may be connected by suitable plugconnections 222 (see also Fig. 16) to sockets 222 of the upper brushesUB of the tabulator.

Depression of the start key S, at this time, will complete the circuitthrough the driving motor TM as follows: from line 222 (Fig. 16), motorTM, relay coil 222. clutch magnet l2, relay coil 22|, wire 222, startkey S, motor control relay contact 222, wire 224, stop key contact ST,cam contact P2 to switch 2|| which is open at this time, thence throughwire 222 (see also Fig. 16a), contacts 222a, wire 221, contacts 222a,wires 222 and 222 to negative side of the line 2|2. The usual holdingcircuits will then operate to maintain this circuit as long as cardscontinue to feed through the tabulating machine.

As the ledger and record cards are fed downwardly through the machineand pass the brushes 22 and UB respectively, these brushes will analyzethe corresponding index point positions of the related columns of thetwo types o! cards. In those positions in which the periorations are inagreement, a circuit will be completed as follows: from line 202 (Fig.16), through cam contact T2, common contact roller of the upper brushes,a perforation in the record card, plug socket 222, plug connection 222(see also Fig. 16a), plug socket 224, control relay coil 222 tocorresponding socket 222, then through plug connection 222, socket 221,brush 22, perforation in the ledger card, common contact roller 2| tonegative side of line 2|2.

During the transit of the cards past their respective brushes, magnets222 will become enercolumns which in the perforations correspond on bothcards and in which suitable plug connections 222 and 222 have been made.

Energization oi a coil 222 will cause closure of its point 222a. and2221 to set up a holding circuit for the coil as follows: from line 222(Fig. 16a), wire 242, relay points 222g, relay coil 222, relay points222D, wire 24|, cam contacts 242, wire 242 to negative side of line 2|2.Contacts 242 are controlled by a suitable cam which may be mounted onmain drive shaft l2, and will release the holding circuit at a latertime in the cycle of operation.

In the system in which the present invention finds particular utility,seven relay coils 222 are provided and each one is connected in seriesbetween brushes 22 and UB as e lained above, so that if the ledger cardclcn data is in agreement with the corresponding data on the record cardall these relay coils will be enerto the classification data in one orrecord columns, will cause the back contacts 222e of such relay coils toremain closed. Upon the subsequent closure of a pair of contacts 244,shaft l2, a circuit will be completed as follows:

coil 222 will draw its amature upwardly and cause opening of theconnection between contacts 222a. These contacts it will be recalled,are in series connection with the operating circuit of the tabulatingmachine which includes the driving motor TM so that opening of thecontacts 222a will cause interruption of further operation of themachine. Such stopping of the machine will inform the operator that thecards are disarranged and he may then correct the arrangement.

If the classification in agreement the ledger card will continue to feeddownwardly until its leading edge engages the roller 12 insulating itfrom its contact block 1| at which time the selected line will be inposition to receive printing from the supplemental printing type bar|02.

Connected in series with the contact roller 12 and block 1| is adifferential relay 241 of which the circuit through one winding may betraced from line 202, wire 242, right hand coil of relay 241, to roller12, wire 242, cam contacts 252, contacts 22 to other side of line 2|2.The circuit through the left hand winding may be similarly traced fromwire 242, relay coil 241, wire 25|, block 1|, to line 2|2 in the samemanner.

Insulation of roller 12 from its contact block data on the two cards is|1| will deenergize the right side of the diierential relay 241 whichwill armature to close relay points 241a which in turn establishes acircuit as follows: from right side of line 2|2. relay points 241a, wire222, clutch magnet l2 to left side of line 202. It will be recalled thatenergization of magnet 52 will disconnect the two pairs of feed rollerson shafts 42a and 42h adjacent to the printing platen 44, from the driveof the machine so that the ledger cards will be held stationary, ceive aprinting impression |02. While the ledger card is being so positionedthe record card in the tabulator is moving past the lower brushes LBand, during such passage, circuits will be completed through the brushesLB to energize printing magnets |02, through circuits which may betraced as follows: from line 2|2 (Fig. 16), printing magnet |22, plugsocket 224, suitable plug connections 252 to a socket 222 of thecorrespondingly selected counter order contacts 2 |2 (closed asexplained above) 'l wire 224 to line 222.

After the record card R. has completely passed the lower brushes LB, thetype bars |22 in the supplemental printing device will have beenpositioned in accordance with the data which is to be printed upon theledger card and printing will automatically take place on the selectedline. At this time also, the control relay 222 will have been reset dueto the opening of contacts 242 and the next record card will have passedthe upper brushes whiles the next ledger card also passed the brushes 20in the supplemental printing device. As long as the classification dataon the two cards being compared, agree, printing will take place on theselected line of the ledger card.

Successive` posting on selected lines diagram. For this type ofoperation of the machine, the

thereupon attract its in readiness to refrom the type bars o comparingmechanism "including relay coils 233 is not utilized and the set updevices controlled by magnets |6| are used instead. In Fig. 16a areshown two horizontal rows of magnets |6| which will hereinafter bedesignated as upper and lower magnets |6|. Upper magnets |6| areconnected to plug sockets 213 which may be connected by suitableconnections 212, with plug sockets 229 of the upper brushes UB (Fig.16). Lower magnets |6| are connected to y203 (Fig. 16), contacts T2,upper brushes UB, plug vice, contact strip |00, contact connection 212,upper magnet |6| wire 215 to line 2|2. As previously pointed out indetail, the

magnets |6I will cause positioning of their assoj ciated contact devicesin accordance with the value of the perforations in the associatedcolumns of the cards. The corresponding con- |6| are electricallyconnected by means oi' individual wires contained in suitable cables216. After the device has beenv set under control oi the cards L and R acomparison is made between'the two settings to determine whether or notthe data analyzed is the same in both ledger end a relay coil 211 isprovided for each column oi' the device, one terminal of which isconnected to the common bar |02 of the associated device. Upon closuneofa pair of contacts 210 controlled by a cam carried by shaft I9, acircuit may be traced through each of the devices which are in agreementas follows: from line 2|2, wire 219, contacts 210, common bar |02 of thelower deblock |0| in the position in which the contacting strip has beenset, connecting wire within cable 216 to the corresponding block |0| ofthe upper device then to the contacting strip |90 and common strip |02of the upper device, relay magnet 211, wire 200 to the other side ofline 203.

If all the analyzed columns are found to be in agreement all the relaycoils 211 will be energized causing closure of their respective contactpoints 211a and opening of their contact points 211b.

If one or more of the relays 211 fails tobecome energized, the'corresponding point 211b will remain closed andupon closure of a pair of contacts 20| a circuit will be completed asfollows: from line 2|2, wire 202, contacts 20|, relay coil 203, wire204, closed contacts 211b. wire 260 to line 203. Relay 263 will closeits points 203a-to complete a circuit from line 2|2, wire 202,

and record cards. To this points 203a, wire 295, solenoid coil 206, wire201, to line 203. Solenoid 206 will close its point 206b to complete acircuit through the magnets 21, 20 from line 203, magnets 21 and 20 inparallel, wire 289, points 2861 wire 215 to line 2|2.v ing of points206a will interrupt the circuit advanced to printing position as thelatter is being analyzed by the lower brushes of the tabulator`analyzing brushes. If these two cards are in disagreement, the ledgercard feeding mechanism will be interrupted but the record card willconmanner to be explained.

If the ledger card is found to be in agreement with the record card itwill continue to feed down- (Fig. 4) will close a pair wire zas, Contactpoints mb, wire 29e, magnet as.

contacts |02 to line 2|2, Energization line 2|2, cam contacts 201(closed at this time), wire 298, contact block 06, perforation in theledger card, contact plunger 05, wire 290, relay coil 300, solenoidmagnet 30|, wire 302, closed relay points 2501;, wire 26| to line 203.Closure of points 30011 will provide a holding circuit for the magnet 56running from line relay points 330e., wire 304, solenoid 203, wire 26|to line 203, points 233:1 will therefore be closed to maintain themagnet 50 energized through a circuit extending from line 2|2, wire 251,points 293a,magnet 56 to line 203. The concurrent reclosure of points23317 will effect a second energization of magnet 89 to space the ledgercard to the next following line. Relay 300 is adapted to close a pair ofpoints 300b at this point to complete a circuit from line 2 I2, wire333, relay points 300i), relay 238 to line 203.

It will be recalled that points 238e of the relay 238 are wired inseries with the operating circuit of the tabulator and the opening ofthese relay points will interrupt further operation of the tabulatoruntil the next line of the ledger card which is to receive printing, hasbeen positioned.

It will also be recalled that the perforation associated with eachprinting line is made adjacent to the next higher line of the ledgercard so that analysis of the last such perforation will bring the lastprinted line into printing position. It is necessary therefore toadvance the ledger card one step further to bring the next blank lineinto printing position. For ihis purpose, the solenoid 33| is of theslow acting type and after these last spacing operations initiated bythe perforations themselves, the return of the armature of the solenoidto its restored position will close a pair of contacts 3:36 establishinga circuit from line 2|2, contacts 306, wire 300, solenoid magnet 29E,wire 26| to line 203. As before, energization of solenoid 293 willeffect a further spacing operation of the ledger card. With the nextline to receive printing in position, the relay points 230a will againclose, restarting the operations of ihe tabulating machine to feed thenext record card past the lower brushes LB and transfer the data thereonto the new line of the ledger card. Following this the momentary closureof contact 230 will effect a spacing operation, through the circuittraced above, to bring the next slank line into position. Each recordcard as it passes through the tabulating machine is compared in turnwith the setting of the comparing device of the ledger card and as longas the two devices are in agreement, data will continue to betransferred to the ledger card under control of the lower brushes.

Upon agreement between the record card and the next ledger card, theseries circuit through the relay point 211 will be completed tointerrupt the further ledger card spacing operation. If thetabulatingmachne is. arranged for group number controlling, it will atthis same time register a change in group number of the record cards andwill either stop or enteriupon an automatic total taking cycle ofoperations during which the card feeding mechanism in both machines willremain inoperative.

As pointed out above, during the total taking operation of thetabulator, the printing crosshead in the supplemental printing devicewill op' erate in synchronism with the operation of the tabuiator typebars and data may be printed upon the ledger cards under control of theac- 2|2, wire 303,l

cumulators of the tabulator. A representative circuit completed at suchtime is as follows:

From line 203 (Fig` 16) contacts 220, wire 22|, cam contacts 2|0, plugsocket 253, connection 255, socket 254, printing magnet |00 to line 2I2.The total or other data contained in the accumulators may thus beprinted on a line of the ledger card when the feeding mechanisms of bothparts of the machine are stationary. Following this total printingoperation, the operation of the card feeding mechanism is resumed and itis desirable to remove the printed ledger card from the machine rapidlysince it has been moved upwardly step by step to receive printing andmay interfere with the leading edge of the next following ledger card.To this end, a circuit is completed through cam contacts 256 to energizerelay coil 250, closing its points 250a so that a further circuit may becompleted as already traced to energize the solenoid magnet 203, whichin turn through its points 263e completes a. circuit from line 2|2, wire205, contact points 233a, wire 200, motor 00, wire 20| to line 203. Theauxiliary motor drives the two pairs of feed rollers adjacent totheprinting platen 00 and which rapidly removes the card from printingposition. The next ledger card is then fed to printing position andlocated at the next printing line in a manner described in connectionwith the first ledger card.

` During the continuous feeding of the ledger cards,

it is desirable to have the step by step mechanism arranged' so as notto interfere with rotation of the feeding rollers. To this end themagnet |00 is provided; and connected, as explained above, by a tape 00with the stepping pawl 3|.

With the parts in the position as shown in Fig. 16a, a circuit iscompleted through the magnet |00 extending from line 2I2, contact |02,wire 301, magnet |00, solenoid contact points 2031i, wire 205, wire 26|,to line 203. When the device is not used for the successive postingoperation described the pawl 0| is held out of engagement with theratchet by the lever 35 as explained in connection with Fig. i2. As alsoexplained, the movement of this lever to its lower position will alsoopen contacts |02 which disable the several circuits associated with thestep by step operating mechanism.

As the next ledger card is advanced to printing position, the comparisondevice will be restored and set up in accordance with the data of thenext following ledger card. This data will in turn be compared with eachsuccessively fed record card in the tabuiator and until a record card isanalyzed, which is in disagreement with the setting obtained lfrom thisnext following ltlger card, printing operations will be permit- Whilethere has been shown and described and pointed out the fundamental novelfeatures of the invention as applied to a single modification, it willbe understood .that various omissions and substitutions and changes inthe form and details of the device illustrated and in its operation maybe made by those skilled in the art without departing from the spirit ofthe invention.
